JPGFILE: gedesert.jpg ZIPFILE: gedesert.zip RENDERER USED: POV-Ray 3.5 TOOLS USED: Photoshop LE for signature and jpeg conversion RENDER TIME: approx. 1.5 hours HARDWARE USED: Pentium 1.7 GHz 512 MB RAM IMAGE DESCRIPTION: Dunes, rocks, the moon - well, my humble try at a desert landscape render. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This image is pure POV-Ray. The dunes are a heightfield made from a quilted pattern. This was the hardest part. Although the final code to make the HF is very short and simple, it took quite some experimenting before I discovered that this pattern makes good dunes. The rocks are isosurfaces based on the rounded_box function with a spline function and some pigment functions added to form the rock shapes. There is one lightsource only and no radiosity. As a result this scene renders quite fast.
